Metso D201138 Control Module

Metso D201138 Control Module (IBC Controller Module – DCS System Rack Card)

 

The Metso D201138 is an IBC (Intelligent Board Controller) module used in Metso / Valmet DNA Distributed Control System (DCS). It is a rack-mounted control processor/interface board used for process logic handling and system-level control coordination inside industrial automation systems.

Product Information

• Brand: Metso (Valmet)
• Model: D201138
• Type: IBC Control Module / DCS Controller Board
• System platform: Metso DNA / ACN / D20 architecture
• Installation: Rack/backplane module (not standalone PLC)
• Function: System control + logic coordination + data processing interface

What it actually is

The D201138 is a system-level control module inside a DCS rack, meaning:

• Works as part of a distributed control architecture
• Handles control logic execution support and system coordination
• Communicates through backplane with I/O modules
• Used in large continuous industrial process systems

It is not a field I/O module and not a simple PLC CPU, but a DCS control node component.

System Role (Simple)

Field instruments (sensors, valves, drives)
→ I/O modules (AI / AO / DI / DO)
→ D201138 control module (this unit)
→ DCS system network
→ operator / engineering station

So it acts like a “central control intelligence board inside the DCS rack ecosystem.”

Important Notes

• Not PLC CPU ❌
• Not I/O module ❌
• Not sensor ❌
• Not power supply ❌
• It is a DCS intelligent control / system controller module (IBC) ✔

Precautions

• Must be used only in compatible Metso/Valmet DNA rack system
• Not interchangeable with standard PLC modules
• Requires correct system backplane configuration
• Version/firmware compatibility is critical in DNA systems
• Handle with proper ESD protection
